This standard applies to the measurement of railway vehicles and their components and serves to demonstrate compliance with metrological product specifications. For measurements which are to be carried out according to the stipulations in the legally regulated area, the respective applicable laws in the current version, e. g. weight and meassures act ("Eichgesetz"), shall apply. The standards of the "State of the railway vehicle" as a whole define the limit state for the safe operation of railway vehicles for normal track width and their components. They shall be applied where the vehicles are operated on a public railway infrastructure. The minimum requirements laid down in the standards for the processes for observing the desired condition of the railway vehicles are also to be applied. In addition, the standards must also be observed in the new design if constructive precautions are to be taken to comply with the operating limit criteria. NOTE 1 The structural design for a maintenance-friendly check of the operating limits must be considered. NOTE 2 The applicability of the standards of the complete vehicle to railway vehicles of other track widths and their components shall be examined in each case.
